Hello!
I have looked at Martin's recent work on "merging" unit tests with R CMD check,
fused it with my and Tony's contributions and developed it a bit further. Take
a look into the attached demo package on how it works.
In essence:
PKG/inst/RUnitTests
|- runRUnitTests.R (script to run RUnit tests)
\- ... (any RUnit test file)
PKG/R/runRUnitTests.R (wrapper function to call
PKG/inst/RUnitTests/runRUnitTests.R)
PKG/man/runRUnitTests.Rd (help with examples! section)
The following can be achieved:
* useRs can run RUnit tests from within R after the package has been installed
on their machine - this info is also given in PKG-package.Rd file to encourage
useRs to test the package
* developeRs can run RUnit tests with:
- R CMD check since examples in PKG/man/runRUnitTests.Rd are tested to work
(test failures or R errors stop the R CMD check!)
- launcing the script PKG/inst/RUnitTests/runRUnitTests.R with Rscript or
R CMD check
I would like to hear any critiques, comments, suggestions, ... on above. Martin
mentioned (privately) that filenames have to much upper case letter, but I
wanted
to emphasize that the main work is being done by RUnit package - not developed
by
me!
Finnally, I would like to argue that from useRs point of view test and unit test
are the same thing and I believe that R would benefit if *all* tests could be
available in similar manner as above. This of course calls for the modification
of
packaging, testing, etc., but could provide more feedback (sure some of it will
be
bogous) on testing on various configurations.
With regards, Gregor
